Is arranged above the hollow needle 81 in the front-rear direction, with its end fixed to the cover 80, and guides the thread 88 extending from the thread spool 82 to the hollow needle 81.

The leaf spring piece 93 is disposed at the upper end of the cover 80 in the left-right direction. The right end is fixed to the cover 80, and the left end contacts the guide pin 92 from above. Here, on the upper part of the cover 80, there is provided a swinging plate 94 which is pivotally supported at the right end thereof via a pivot shaft 94a oriented in the front-rear direction, and which can swing. And a leaf spring piece 93 are fixedly provided. The guide pin 92 is used to hold the fixed portion 31 even when the swing arm 40 swings up and down.
c and the vertical position thereof is fixed.
2 and the hollow needle 81 swing up and down together with the swing arm 40. Accordingly, the path of the thread 88 from the thread spool 82 to the hollow needle 81 is changed by the guide pin 91. In addition, the guide pin 92,
The leaf spring piece 93, the rocking plate 94 and the like correspond to the balance means.

A locking piece 95 capable of locking the lower end of the rocking plate 94 is fixed to the cover 80. The rocking plate 94 is locked with the rocking plate 94 locked to the locking piece 95. The sewing cartridge 5 is stored in the cover 80 and becomes ready for use. From this state, as shown by a chain line in FIG.
When the swinging plate 94 is swung upward, for example, when the thread 88 comes out of the hollow needle 81 upward, the thread 88 is moved to the hollow needle 8.
1 can be passed relatively easily.

The presser foot 85 is formed in a disk shape, and is disposed on the lower end side of the hollow needle 81 outside the cover 80. A needle hole 85 a through which the hollow needle 81 can be inserted is formed in the presser foot 85, and the lower end of a guide pin 96 is fixed to the right side thereof. The guide pin 96 is slidably engaged with an engaging member 97 fixed to the right side of the hollow needle 81 inside the cover 80, and the guide member 96 guides the presser foot 85 together with the guide pin 96 so as to be able to move up and down. Have been.

A compression coil spring 86 is mounted on the guide pin 86 between the cover 80 and the presser foot 85, and the presser foot 85 is elastically urged downward by the compression coil spring 86. Bend 96a at the upper end of guide pin 96
Is engaged with the vertical groove 97a of the engaging member 97, and since the bent portion 96a normally engages with the lower end of the vertical groove 97a, the presser foot 85 is slightly lower than the lower end of the hollow needle 81. And the presser foot 85 allows the hollow needle 8 outside the cover 80 to be positioned.
The lower end of 1 is guarded. Here, presser foot 8
5 corresponds to a guard member.

At the time of sewing, when the sewing cartridge 5 is lowered, the presser foot 85 presses down on the cloth 70 and becomes substantially stationary. In this state, the hollow needle 81 is lowered with respect to the presser foot 85, and the tip of the hollow needle 81 is moved to the cloth. Pierce 70. Now, swing arm 4
A plurality of sewing cartridges 5 that can be attached to and detached from the sewing cartridge 5 are prepared. The sewing cartridges 5 accommodate threads of different colors, respectively, so that a colorful embroidery pattern can be formed.

The stitches formed on the cloth 70 by the sewing operation of the sewing device 1 will be described with reference to FIG. With the embroidery frame 4 on which the cloth 70 is attached and the sewing cartridge 5 attached to the sewing apparatus main body 1, the sewing drive cartridge 12 is moved up and down by the cartridge drive mechanism 12 while being moved to the embroidery frame 4 by the embroidery frame drive mechanism 11. Move. However, the sewing cartridge 5 swinging up and down
When the hollow needle 81 is pierced into the cloth 70, the embroidery frame 4
Is stationary. At this time, the tip of the hollow needle 81 is located at the end of the hollow needle 81 on the swing center side of the swing arm 40, thereby preventing the cloth 70 from shifting. Hollow needle 81 is cloth 70
The moment of piercing the cloth 70 is substantially perpendicular to the cloth 70.

When the hollow needle 81 of the sewing cartridge 5 descends and pierces the cloth 70 including the elastic membrane 71, a thread 88 extending from the tip of the hollow needle 81 and penetrating the cloth 70 together with the hollow needle 81 is formed. Is held on the cloth 70 by frictional resistance received from the elastic film body 71 of the cloth 70. Therefore, the hollow needle 81
After penetrating the cloth 70, the thread 88 inside the hollow needle 81 is not subjected to friction from the cloth 70 until it reaches the lower limit position shown by the chain line in FIG. Without pulling the embroidery pattern 75, the hollow needle 81
Thread 88 is smoothly fed out from the end of the thread.

Next, when the hollow needle 81 rises from the lower limit position and its tip comes off the cloth 70, a thread 88 extending from the tip of the hollow needle 81 and penetrating the cloth 70 from below the cloth 70 together with the hollow needle 81 is formed. The free thread 76 is formed on the back side of the cloth 70 by the upper thread 88 in the same manner as described above. Thereafter, until the hollow needle 81 reaches the upper limit position, the thread 88 is paid out from the tip of the hollow needle 81, and then the cloth 70 is moved and driven in the X and Y directions together with the embroidery frame 4, and the hollow needle 81 is moved. When the user descends from the upper limit position and pierces the cloth 70, a stitch of the embroidery pattern 75 is formed on the surface of the cloth 70.

The above operation is continuously performed, and the thread 88 is attached to the cloth 70.
Is penetrated a plurality of times, an embroidery pattern 75 is formed on the surface of the cloth 70, and a plurality of free loops 76 are formed on the back side of the cloth 70 and remain. Then, when the double-sided tape 77 as a fixing material for fixing the plurality of free loops 76 is adhered to the back surface of the cloth 70, a pattern sewing cloth 78 as a pattern workpiece shown in FIG. 14 is formed.

Therefore, since the free loop 76 is not pulled out, the embroidery pattern 75 on the surface of the cloth 70 is not frayed and stabilized without fixing the thread with another thread or a stitch before and after the thread. I do. Then, the pattern sewing cloth 78 can be used as an emblem and adhered and fixed to various objects via the double-sided tape 77. In addition to the double-sided tape 77, the cloth 7
Various adhesives or adhesives may be applied in layers on the back surface where the zero free loop 76 remains, or tapes of these various adhesives or adhesives may be formed, and the tape may be used on the back surface of the cloth 70. A plurality of free loops 76 may be secured.

Since a large number of free loops 76 are located on the back side of the cloth 70, the double-sided tape 7
When 7 is attached, irregularities occur on the double-sided tape 77. Therefore, when the cloth 70 is applied as an emblem or the like to the garment via the double-sided tape 77, the garment to be affixed is soft and such an emblem is easily peeled off. Can be improved. Whether the unevenness is formed for each individual free loop or a plurality of free loops depends on the material of the thread or the double-sided tape.

4) is executed, and the embroidery frame drive mechanism 11 and the cartridge drive mechanism 12 are controlled based on the pattern data of one pattern portion, and the pattern portion is sewn on the cloth 70.

When one pattern portion is formed, sewing of the pattern portion is completed (S15), and when the thread color of the pattern portion to be sewn next is changed, the sewing cartridge 8 containing the thread 88 of that color is used. Replace. In this case, before the currently mounted sewing cartridge 5 is removed, for example, if a thread change is instructed by operating a predetermined button of the controller 7 (S16; Yes), then, thread trimming and sewing are performed. A thread loosening process (S17) is performed to replace the cartridge 5 for use.

When the sewing cartridge 5 is not replaced,
There is no need to execute the thread slackening process in S18. When the thread change is not instructed (S16; No), the process returns to S13. If the start / stop switch 16 is turned on after the sewing interruption (S15) (S13; Yes), the sewing process (S14) is executed and the next process is executed. Is formed.

The yarn slackening process will be described. In this thread loosening process, after the sewing is completed, the embroidery frame 4 is moved from the sewing completion position to the movement limit position in the movement area 38 (see FIG. 6) in order to pull out the thread 88 from the thread block 82 in the sewing cartridge 5. After that, the embroidery frame drive mechanism 11 is controlled so that the thread 88 between the hollow needle 81 and the cloth 70 is slackened. The thread slack control program for that purpose is the sewing device 1

As another modification, as shown in FIG. 25, a cutting mechanism 140 for cutting the thread 88 between the hollow needle 81 and the cloth 70 after the sewing is completed may be provided. This cutting mechanism 14
0 is a scalpel 141 pivoted around the vertical axis and
141 has a link 142 whose one end is rotatably connected around a vertical axis. The link 142 is driven substantially in the front-rear direction by an actuator (not shown), and the knife 141 rotates,
As a result, the scalpel 141 is moved between the hollow needle 81 and the cloth 70 by the thread 8.
8 can be hooked and cut. The cutting mechanism 140 is a thread cutting device (Japanese Patent Application Laid-Open No.
Since the structure is the same as that of JP-A-239176, detailed description is omitted.

By providing the cutting mechanism 140, the embroidery frame driving mechanism 11 moves the embroidery frame 4 to a thread cutting position where the slack thread 88 can be cut by the cutting mechanism 140 after the thread loosening process. Is controlled, and then the cutting mechanism 140 is driven to cut the loose thread 88.

The thread cutting control program for controlling the embroidery frame drive mechanism 11 and the cutting mechanism 140 to cut the thread 88 may be stored in the ROM 6b of the sewing apparatus 1,
It may be configured to be stored in the DVD 100 and supplied to the control device 6 of the sewing device 1 as appropriate. The thread cutting position of the embroidery frame 4 is determined based on the sewing completion needle drop position at which the hollow needle 81 has finally dropped on the cloth 70 and the data obtained by moving the embroidery frame 4 to loosen the thread 88. Is calculated.

In the above embodiment, the guide member 69 is provided so as to protrude outside the safety cover 3 as shown in FIG. 3, but instead of this guide member 69, as shown in FIG. A guide member 150 may be provided inside. In this case, the embroidery frame insertion hole 151 needs to be large enough to handle. However, since the size of the embroidery frame insertion hole 151 is large, the function as a cover is somewhat reduced. Therefore, it is better to provide the guide member 69 on the outside. When the guide member 69 is provided on the outside, the area inside the safety cover 3 can be effectively used for movement of the carriage 18 for sewing.

In any of the embodiments described above,
An opening for mounting the embroidery frame 4 is an opening. As shown in FIG.
The cover 156 is configured to be rotatable so that the lid 156 is in a position to close the passage portion of the embroidery frame 4 by its own weight. As shown in FIGS. 27 (a) and (b), when the embroidery frame 4 is inserted, At the time of removal, the cover 156 may be configured to be pushed by the end of the embroidery frame 4 and rotate to open the passage portion of the embroidery frame 4. This lid 156 further enhances safety.

In the above-described embodiment, when the carriage 18 has moved to the foremost position, the carriage 18 is located immediately below the hollow needle 81 and is located deep, and it is difficult to confirm the location of the carriage 18. In order to make the carriage 18 easily attachable to the carriage 18, the carriage 18 may be configured to move to an advanced position where the carriage 18 approaches the safety cover 3 or the like (for example, the carriage 18 is moved to a position immediately behind the guide member 69). Or to a position protruding from the safety cover 3). In this case, the movable area 38 for sewing the carriage 18 does not coincide with the movable range,
It is difficult to imagine that the moving mechanism of the embroidery frame 4 is being used to the maximum extent, and it is better that the moving area 38 for sewing and the movable range of the carriage 18 match.

The safety cover 3 may cover the entire movable range of the carriage 18 so as not to touch the embroidery frame 4 by hand, but instead of the safety cover 3, as shown in FIG. A cover 160 that covers at least a part of the possible range 162 may be provided. In this case, a cover 161 that covers the entire sewing apparatus main body 2 may be separately provided. The cover 160 that covers at least a part of the movable range 162 and the cover 161 that covers the entire sewing device 2 are also translucent or transparent, so that the sewing state can be visually recognized.

The formation of a stitch by the hollow needle 81 will be described in detail below. As shown in FIG. 29A, when the hollow needle 81 pierces and penetrates the cloth 70, FIG.
As shown in FIG.
Is formed. The center 169 of the arc of the cut 165 is located on the side opposite to the center of the swing of the swing arm 40 with respect to the tip of the hollow needle 81. At the position to be near the center of the cut 165, the tip of the hollow needle 81 is first pierced, and then moves downward in a locus of an arc due to the swing of the swing arm 40, and penetrates the cloth 70. This produces an arcuate cut 165. The yarn is held by the cut surface of the arc-shaped cutout 165 of the cloth 70.

In the sewing, since the leading end of the hollow needle 81 and the swing center of the swing arm 40 are located on the left and right (in the extending direction of the swing arm 40), the area is so-called a fixed stitch. In the case of sewn, the sewn part may be folded back and sewn. As shown in FIG. 30, it is most desirable to sew in one of the directions a perpendicular to the sewn direction (the depth direction of the sewing apparatus main body 2). That is, in a relative movement that is continuous in a certain direction, the hollow needle 81 and the embroidery frame 4 are moved in parallel with the arrangement direction of the arcs. Then cut 16
The tangent line at the center of the circular arc in FIG.
165 are successively formed. If sewing proceeds in the extension direction of the swing arm 40 passing through the distal end of the hollow needle 81, the thread 88 may be cut by being stepped on the distal end of the hollow needle 81.

Therefore, in order to shift the thread 88 from the tip of the hollow needle 81, as shown in FIG.
It is necessary to shift the swing arm 40 about 5 degrees with respect to the extension direction b of the swing arm 40 passing through the foremost part of the swing arm 40 in a direction orthogonal to the extension direction b (a direction toward the back of the sewing apparatus main body 2). That is, the position of the needle drop before and after is shifted so that the yarn is shifted from the leading end. The embroidery frame drive mechanism 11 is controlled so as to prevent thread breakage. In order to realize the above operation, the sewing device 1 is controlled so that the embroidery frame 4 (the cloth 7
0) may be stored in the ROM 13b of the control device 13, or at least a part of the control program may be stored in the computer (the control device of the game machine 6 or the sewing device 1). 13 or a personal computer) may be stored in a recording medium such as a DVD.

Optical storage medium, a magnetic storage medium such as a floppy (registered trademark) disk, and a semiconductor storage medium such as a flash memory).

In the above-described embodiment, it is assumed that the sewing data is stored in the external storage medium in advance, but the sewing data is created and calculated by the CPU of the sewing apparatus main body 2 and the game machine. Is also good. For example, color image data of a game is decomposed for each color, an area for each color is specified,
Identify it as a sewing area for each color, create sewing data that sew the area by tatami sewing, and create sewing data for each color. create. To capture image data in this manner, a video capture function (a print screen function in a personal computer) is sufficient. The sewing order may be sequentially determined based on the size of the area, the brightness of the color, and the like, but it is preferable that the contour is sewn last.

A purchaser of this product may want to obtain an entity such as a prize (software is not something that can be touched by hand, but prize is something that is actually touched) related to the software of a home game, or It is a person who is envious of such children. In other words, regardless of whether or not they are interested in sewing, the purchasers of household games who want to obtain prizes and the like. Furthermore, prizes and the like that are desired to be obtained are not limited to those related to home game software. The prizes that can be obtained are not limited to one specific company's software, but also game machines and other entertainment-related devices of many other manufacturers, entertainment itself and related software (slingshots, slots, entertainers, TV programs, sports programs, etc.). , Music, etc.).

In other words, this sewing apparatus is an apparatus for processing a certain workpiece in order to manufacture premiums and the like. Then, if a prize or the like can be provided in the same manner, the data supply device connected to the sewing device main body 2 is not limited to a home-use game. If the data supply device has a function of handling data, an embroidery sewing machine, a computer sewing machine, a radio-cassette, a satellite broadcasting reception Tuner, karaoke terminal (with or without communication function), facsimile, mobile phone, TV, VCR, music CD player,
Various devices such as an 8 mm video camera, a digital camera, and a computer may be used, and data transmission and reception with the sewing device main body 2 may be performed via a cable, but may be performed wirelessly (including infrared rays and the like). .

For example, when a satellite broadcast receiving tuner is used, the main sound is used in the advertisement during the advertisement broadcast of the sewing apparatus main body 2 itself, the company of the manufacturer, or other products, and the sound of the advertisement is used. The data and the program for the sewing apparatus main body 2 can be received by the auxiliary voice which is not used. The receiving tuner may process the received data or program and control the sewing apparatus main body 2 to perform sewing. However, the sewing apparatus main body 2 may be processed via another device such as the above-mentioned home game machine. May be supplied or controlled.

When the sub-audio is used, when the image is recorded on the VCR, the data and program cannot be used unless the reproduction speed is normal for watching the advertisement of the recorded image. Alternatively, the advertisement effect may be ensured. If the sewing machine is used as a data supply device, it is possible to sew patterns built in the sewing machine and patterns of an external storage medium mounted on the sewing machine.
Editing is performed using a display unit and operating members on the sewing machine.

In the embodiment described above,
Although the data supply device connected to the sewing device main body 2 is directly connected to the cable, the data supply device may be connected via a connection conversion member so as to be connectable to various devices as described above.

Embroidery with an industrial sewing machine)
And may receive the prize (mail the prize). In addition, a special machine may be installed in a convenience store, a game center, or a sewing machine shop, where prizes and the like may be manufactured. In this case, the progress of the game is stored in the flash memory card inserted in the home game, and it is determined whether or not the user has the right to acquire a prize based on the stored information.

[0136] From the implications as a prize, a relevance is provided between entertainment such as games and prize acquisition. For example, the prize obtained depends on the progress of the game, or the number of acquisitions (the number of personal productions or the total number of prizes in the world) is limited in order to maintain scarce value. Alternatively, the score of the game may be embroidered, or the date and time when the game has been won may be embroidered. Furthermore, the names and characters are embroidered along with their scores, date and time, and ranking.

It should be noted that an embroidered emblem created with a thread and a cloth has a higher quality than printed matter and is valuable as a prize. In addition, when it is attached to clothing, if it is made of a thread or the like, there is no sense of incongruity, and it will be the best thing to attach to the clothing. Because it is double-sided tape, it is easy to put on and take off. Instead of the double-sided tape, a detachable fastener made of a support having a hook and a loop may be used. When the emblem is attached to the garment with a double-sided tape or a fastener, the emblem can be easily removed at the time of washing the garment.

As described above, the emblem which is the sewn product of the present invention can be obtained if the double-sided tape is not attached to the back side.
Since the thread can only be settled on the fabric to the extent that it can be unwound, after sewing with multiple threads, one of the threads is pulled from the fabric and removed, so that it can be applied to the fabric before and after removing the thread. The remaining stitches may be reduced so that different patterns remain on the fabric.

For example, a pattern in which a circular area is sewn with a plurality of threads of one color is sewn on a cloth, and when one of the threads is removed, the remaining thread turns into a circle. The family crest is drawn as if a picture of the family was drawn. This crest is
It may be a family crest of a character appearing in the game as described above. It should be noted that a plurality of threads of the same color may be used and some of them may be removed, but it is also possible to sew with a plurality of threads and remove only the thread of a specific color. The sewing method according to the present embodiment is convenient because there is no need to remove the lower thread as compared with the sewing method using the lower thread.

In this sewing method, the thread is easily pulled out, and the embroidery frame 4 is moved so as to loosen the thread for thread cutting or taking out the embroidery frame. Stitches that can be frayed when thread trimming or embroidery frame removal are separate from the pattern (or as part of it)
It may be formed.

In the above-described embodiment, the thread trimming is manually performed using scissors separate from the sewing apparatus main body 2, or the sewing apparatus main body 2 is provided with an automatic thread trimming mechanism having an actuator such as a motor. It may be configured to perform thread trimming automatically.However, a scissor having a movable blade is provided at a predetermined position in the safety cover, and by operating a manual operation lever, a force of the operation is linked to a link mechanism or the like. And the movable blade may be moved for thread cutting. In this case, the embroidery frame is moved to a position near the predetermined position of the movable blade before the thread trimming. Further, a configuration having only a fixed blade, such as a simple cutter blade, may be used instead of the movable blade. Such a thread trimming mechanism without an actuator can simplify the configuration of the sewing apparatus main body 2 as compared with a configuration with an actuator.

It is needless to say that various modifications can be made to the above embodiment without departing from the scope of the present invention.
